Title Showing Herbig Haro object HH 450

Description When I first processed this image, I was distracted by the small red "artifact" in the far lower right, immediately below the blue reflection nebula vdB 152. Further image reviews disclosed that this is actually HH 450, a Herbig Haro object. This version restores that object.
